To all whom it may concern.-

Be it known that I, CASPER W. MILE S, a citizen of the United States, residing at Cincinnati, in the county of Hamilton and State of Ohio, have invented certain new and useful Improvements in Box- Forming Machines; and I do hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to improvements in boX-formingmachines. One of its objects is to provide improved mechanism for forming the shooks composing thebottom, sides, and top of packing-boxes and, forbinding the several slats or boards composing the same together by means of metal bands.

Another object .is to provide improved means for clenching over the tongues which bind the metal bands to the slats and for feeding the bands and slats during the clenching operation.

Another object is to provide improved means for automatically severing the metal bands into suitable lengths to form the shooks and to trim the ends or form tongues at the extreme ends of the bands which serve to bind the ends of the bands-to the slats of the shook, so as to prevent the projection of sharp corners or rough ends, which would be liable to injure the workmen in handling the same.

Another object is to provide improved mechanism whereby the cut-off mechanism may be set to cutoff bands of varying lengths, according to the size of box which it is desired to make.

It also consists in certain details of form, combination, and arrangement, all of which will be more fully set forth in the description of the accompanying drawings, in which- Figure l'is a central longitudinal section through the machine. Fig. 2 is a diagram in plan View showing the preferred manner of severing the bands into sections of proper length to form a shook. Fig. 3 is a perspective View of the respective ends of the bands and the teeth formed thereon. Fig. 4 is a detail section through one of the band-feeding wheels. machine on line z z of'Fig. 1.

Fig. 5 is a cross-section through the Fig. 6 is a de-.

. tail sectional view through the band-feeding rollsand guides.

The mechanism illustrated is designed to form shooks to be used-for the bottom, sides, and top of packing-boxes, said shooks being composed of a series of slats or boards A, which are firmly bound together into a composite whole by means of metal bands B, which are secured to the slats at short intervals by means of tongues 13, formed integral with the bands, and which pass through the slats and are clenched upon the opposite side thereof, the shook and ends of the box being shipped in knockdown form and put together whenever desired for use.

D represents the slat-hopper; E, chain belts having teeth E, by means of whichthe slats are severally and regularly fed from the hopper. The chains are supported upon sprocketwheels e e, the sprockets 6' being loose upon the shaft 6 which is adjustable to tighten the chain.

The metal bands are first fed between the punch-rolls F G, which strike up the teeth B at regular intervals. The bands then-pass between the cut-off rolls I J, which are normally at rest, but which at appropriate intervals are caused to revolve a single revolution at a time in order to cut the bands into proper lengths to form the shooks and to trim the ends and form the tooth O at the ends of the bands. The bands then pass over the rolls K, being held in place thereon by means of magnets L, assisted by the guides L, whereby the bands are delivered in contact with the upper face of the slats upon the chain belts and the teethof'the bands are caused to perforate the slats, which are supported on the under side opposite the rolls K by means of the rolls M. In order-that the rolls K may grip the slats, they are slightly recessed in the center to receive the bands. The rolls K M assist the chain in feeding the slats during the act of clenching.

N represents clenching bars which are mounted loosely upon the shafts between the rolls M, the lower ends being held to the crossbar P by means of the eyebolts Q. The uppercnds of the clenching-bars are provided with steel shoes or, which bear against the under side of the slats as they are gripped between the rolls K M and slide on the under side of the slats, so as to clench over the ends of the teeth and to bed them into the under face of the slats. The shocks thus formed are preferably delivered onto the belt R and fed by means of belts or rolls direct to the drying-room and are then ready for use. By severing the bands before applying them to the slats, so that the ends of the bands will not project beyond the end slats of the shook, the ends of the bands are closely attached to the end slats of the shook, the shooks are delivered separately, and no sharp corners or rough edges are left project ing to injure the workmen in handling the shooks or boxes.

The machine is preferably driven from a belt-pulley on the shaft S, from which motion is transmitted by means of idler-gear 1 to the shaft 0, which is in turn geared to drive the shaft K of the rolls K. The journal-boxes of the shaft K are preferably held down with a yielding pressure by means of springs The rolls F and shaft F are driven from the shaft S through intermediate gears 4.

U represents a clutch member mounted loosely upon the shaft 1, which clutch member U is continuously driven through intermediate gear from the gear-driving shaft F and should be arranged so as to drive the rolls I J at the same peripheral speed as the rolls F.

V represents a clutch member keyed to the shaft I and provided with a notch o, adapted to be engaged by the spring-pawl 7, carried by the clutch member U.

8 represents a lever pivoted at 9 and provided with a lug 8, adapted to lie normally in the path of the lug 9 on the pawl, so as to retract the pawl and prevent it from engaging with the notch in the clutch member V.

10 represents a cam on shaft controlling the movements of the lever 8, so as to retract it at appropriate intervals from the path of the pawl to permit the pawl to engage and turn the rolls I J and to return the lever 8 again to normal position after the rolls I J have made one revolution. The cam 10 is revolved by means of a gear 11, splined to the outer end of the shaft F and adapted to slide laterally thereon.

12 represents a bifurcated lever pivoted on the shaft F and carrying between its divided arms a gear 13, which by sliding the lever and gears 11 13 along the shaft F is adapted to engage any one of a cone of gears 14: on the shaft p, thereby imparting a rela tively faster or slower movement to the cam 10, which causes the clutch to be tripped and the rolls I J to be revolved at shorter or longer intervals to cutthebaudsinto longerorshorter sections according, to the length of shook required, the dies of the rolls I J being preferably arranged to cut the hand between two adjacent teeth of the band, as indicated in Fig. 2. The handle end of the lever 12 is adapted to be locked by means of a pin 15 to a bracket 16 to hold the gears in engagement. The lever 12 is a bent lever, which has its bifurcated end pivoted on the shaft F on opposite sides of the gear 11. At the bend of the lever is a small shaft on which is journaled the gear 13, while the lower free end of the lever is adapted to be locked to the arm 16, so as to hold the gear 13 in mesh with one of the gears 14, as shown in Figs. 1 and 5.

The upper rolls J have an annular recess {except at the point where the dies are located to permit the passage of the teeth B. The size of rolls K is such that the forward end of the band sections come in contact with the slats before the rear end of the band-sections are severed, thereby insuring a steady and regular feed of the band-sections. The guides 17, which are preferably strips of non-magnetic material on opposite sides of the projecting teeth B of the bandsections, serve to guide the bands from the rolls F G to the rolls I J, and the guides L, as shown in Fig. 1 1, conduct them to the rolls K and hold them in contact therewith and against lateral displacement.

In Fig. 4 I have shown in detail the magnets L, which serve to hold the band-sections upon the rolls K. They are preferably permanent magnets, as shown in the upper portion of Fig. 4, and are provided with nonmagnetic sleeves 21. If desired, however, electromagnets such as shown in the lower portion of Fig. 4 may be employed.

22 23 represent gears for driving the rolls I J in unison.

In Figs. 11,12, 13 I have illustrated one form of dies and the manner of severing the band into sections. As shown in Fig. 11, the projection 37 of the male die 39 enters a recess 36 in the opposite die 35, thereby forming the tooth O. The slightly-raised face 38 of the male die enters a corresponding recess 40 in the face of the opposite die to sever the band and trim off the corners, as indicated in Fig. 2. 11 represents the edge for cutting the tongue 0, which is flush with the face of the roll J, and 42 represents a recess in the raised face 38 to receive the same. Other forms of dies may be used, depending on the style of cut desired.

The several punching, severing, and feeding rolls and clenching-bars are adapted to be adjusted laterally upon their shafts to form boxes of different sizes.

If desired, the tooth C may be omitted from the end of the band and the severed ends of the band concaved, as shown in Fig. 10, or

otherwise trimmed, so as to present no sharp points or rough edges, the end teeth B in that case serving to hold the end of the band-section in close contact with the slats.

By arranging the band-severing rolls so as to sever the bands into sections before applying the bands to the slats I am enabled to cut the bands shorter than the slat portion of the shooks and to prepare the ends of the bands so as to securely attach them to the end slats, and thereby avoid the projection of any sharp corners or rough edges which might injure the workmen in handling the shooks or boxes.
